PIVOT FOR DECK-SASHES.

Specification of Letters Patent.

Application filed March 2, 1911.

To all whom it may concern:

Be it known that I, J ()HN R. Btmnows, a citizen of the United States, residing at Wilmington, in the county of Newrastle and State of Delaware, have invented certain new and useful Improvements in Pivots for Deck-Sashes, of which the following is a specification.

My invention relates to improvements in pivots for deck sashes, and more particularly to the hinged or pivotal mounting therefor, the object of the invention being to provide improved pivotal mounting which enables adjustment of the sash to nicely fit the frame, and which permits the sash to be readily removed and replaced as desired without disfiguring the framework in the slightest.

A further object is to provide improved brackets secured to the framework and limiting the pivotal movement of the sashes and provide improved means for holding the sashes at various pivotal adjustments, and yieldingly holding the same in closed position.

"With these and other objects in view, the invention consists in certain novel features of construction and combinations and ar rangements of parts, as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1, is a view in transverse section through a deck sash showing it in closed position in its frame, and showing in elevation my improved pivotal mounting. Fig. 2, is a view at right angles to Fig. 1. Fig. 3, is a view similar to Fig. 1, but showing the sash in open position. Fig. 4;, is a view in section on the line 14 of Fig. 1, and Fig. 5, is a view in section on the line 5-5 of Fig. 1.

1, represents a deck sash and 2 the ear frame, in which the sash is mounted. The pivotal mounting of the sash at both ends is precisely alike, and hence the illustration and description of one end of the sash, applies alike to both.

To the inner face of frame 2, a casting 3 is secured by screws 4:. This casting 3 is preferably of the peculiar shape shown, that is, it is straight throughout the greater portion of its length as shown at 5, and serves as an abutment for the sash in closed position. The lower edge of the casting inclines as shown at 6, and serves as an abutment to limit the opening movement of the Patented Dec. 19, 1911.

sash. Both of these edges 5 and 6 are strengthened by a laterally projecting web or flange which is integral with the casting.

To the upright bar of the sash 1, a bracket 7 is fixed, and this bracket is provided centrally with an outwardly projecting arm 8. At a point approximately midway the length of arm 8, said arm is provided with a bearing 9 for the reception of a journal screw 10, the latter having a smooth portion where it projects through bearing 9 and provided at its outer end with an enlarged head 11, constituting a finger hold for turning the screw. This screw 10 is made with a pointed end 12, which readily finds its way into a threaded opening 13 in casting 3,

the frame 2 recessed as shown at 1 1 back of said opening 13 for the accommodation of the screw 10 to permit of longitudinal adjustment of the latter.

To hold the sash in closed position, and at various points of pivotal adjustment in opening, I provide a spring 15 which is of flat sheet metal secured to the frame by screws 16 and having its end bent and corrugated as illustrated at 17. This corrugated end of the spring presses toward arm 8 and against the end of a screw 18, which is projected through a threaded opening 19 in the arm 8. hen the saslnis opened or closed, the end of the screw 18 rides the corrugations in the spring, and when stopped will always project into one of the hollows, except when the sash is completely closed, when the end of screw 18 will bear against an inclined face as shown most clearly in Fig. 4. so as to tightlv hold the sash in its closed position, exerting a constant spring cam action to hold itin this position and exclude the outside air.

It will be noted that with my improvements, the sash may be adjusted. in the frame by turning screw 10, so that the sash may be exactly positioned in the frame, insuring the same frictional engagement at both ends of the sash, and by adjusting screw 18, the bent corrugated portion of the spring 15 is forced inwardly. and the tension therefore of said spring is increased or decreased as the case may be.

While the brackets 7 may be secured to the sash in various ways, I prefer to secure them by means of screws 20, which project through openings in the sash. and screw into threaded openings 21 in the brackets. In other words, openings are provided through the upright bars of the sash, and the heads of the screws are on the inside, preferably countersunk, while the threaded ends of the screws engage threads in the openings 21. This enables the sash to be removed from inside of the car by simply removing the screws 20, so that in the event a pane of glass is broken, the sash may be removed, reglazed, and replaced from the inside of the car.

Various slight changes might be made in the general form and arrangement of parts described without departing from my in vention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Let-- ters Patent is:

1. A mounting for deck sashes comprising two members, one member adapted to be secured to the frame, and having a vertical edge and an inclined edge, the former constituting an abutment for the sash when closed, and the latter limiting the opening movement of the sash, the other member adapted to be secured to the sash, and a screw -threaded journal pin projected 'through said last-mentioned member and screwed into the first-mentioned member, substantially as described.

2. A mounting for deck sashes comprising two members, one member adapted -to be secured to the frame, and having a vertical edge and an inclined edge, the former constituting an abutment for the sash when closed, and the latter limiting the opening movement of the sash, the other memberadapted to be secured to the sash,-and a screwthreaded journal pin projected through said last-mentioned member and screwed into the first-mentioned member, a corrugated spring adapted to be secured to the frame, and a screw in said last-men tioned member engaging the corrugated spring, whereby said members are held in closed or open relation with each other, substantially as described.

3. A mounting for deck sashes comprising a casting adapted to be secured to a frame, and having a screw-threaded opening therein, a bracket adapted to be secured to a sash, an arm on the bracket having an opening therein, a screw-threaded journal located in the opening in the arm, and adapted to screw into the opening in the casting, a corrugated spring adapted to be secured to the frame, and a projection carried by said arm adapted to engage said spring, substantially as described.

4. A mounting for deck sashes comprising a casting adapted to be secured to a frame, and having a screw-threaded opening therein, a bracket adapted to be secured to a sash, an arm on the bracket, having openings therein, a screw-threaded journal located in an opening in the arm, and adapted to screw into the opening in the casting, a corrugated spring adapted to be secured to the frame, and a screw pro jected through the other of said openings in the arm and engaging the corrugated spring, substantially as described.

5. The combination with a frame and a deck sash therein, of a casting secured to the frame outside of the deck sash and having a vertical edge and an inclined edge, the former serving as an abutment for the sash when closed, and the latter limiting the opening movement of the sash, a bracket secured to said sash, an arm on said bracket having a bearing between its ends, a thumb screw constituting a journal projected through said bearing and screwed into a threaded opening in the casting, a spring secured to the frame and comprising a strip of spring metal bent upon itself, the outer portion of said spring corrugated, and a screw projected through the arm and engaging the corrugated portion of said spring, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
